Name:China supplier FL400A-LP2-50 Ohpir Fan-Cooled thermopile sensor
Type:FL400A-LP2-50
Manufacturer:The FL400A-LP2-50 is a fan cooled thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 50mm aperture and can measure power from 100mW to 400W continuously and to 500W intermittently.
Product Description:

Ohpir FL400A-LP2-50 400 W Fan-Cooled thermopile sensorwith 50 mm Aperture|China supplier


The FL400A-LP2-50 thermopile sensor is a fan cooled laser power and energy thermal sensor for high power density and long pulse lasers. It has a 50 mm aperture and can measure optical power from 100 mW to 400 W continuously and to 500 W intermittently. It can measure energy from 250 mJ to 600 J. Its high damage threshold LP2 coating covers the spectral range 350 to 2200 nm and 10.6 µm.


  • LP2 type 350 to 2200 nm absorber for long pulse lasers
  • Fan-cooled 0.1-400 W continuous power measurement
  • 250 mJ to 600 J pulse energy measurement
  • 500 W power measurement intermittently
